#45436 [NEW]: cloned Objects can't be passed by value to a function
From: jtrelfa at gmail dot com
Operating system: Windows XP
PHP version: 5.2.6
PHP Bug Type: Class/Object related
Bug description: cloned Objects can't be passed by value to a function
Description:
------------
I was trying to fill an array with objects by cloning the object as the
argument in the function.
I read
http://us2.php.net/manual/en/language.oop5.basic.php#language.oop5.basic.new
It mentions that passing the object to a function is a reference - but why
doesn't cloning work, either? I tried two different ways to pass a cloned
object, but still got a referenced object rather than a cloned one.
Reproduce code:
---------------
class Foo {
var $ar;
function __construct() {
$this->ar = array(0,0,0);
}
}
//use clone keyword
$obj = new Foo();
$bar = array_fill(0,2,clone $obj);
print_r($bar);
$bar[1]->ar[0] = 1;
print_r($bar);
//a different way to clone
$obj = new Foo();
$bar = array_fill(0,2,$t = clone $obj);
print_r($bar);
$bar[0]->ar[0] = 1;
print_r($bar);
Expected result:
----------------
Array
(
[0] => Foo Object
(
[ar] => Array
(
[0] => 0
[1] => 0
[2] => 0
)
)
[1] => Foo Object
(
[ar] => Array
(
[0] => 1
[1] => 0
[2] => 0
)
)
)
Actual result:
--------------
Array
(
[0] => Foo Object
(
[ar] => Array
(
[0] => 1
[1] => 0
[2] => 0
)
)
[1] => Foo Object
(
[ar] => Array
(
[0] => 1
[1] => 0
[2] => 0
)
)
)
